Buys måle python trom a snake dealer who tells him that the snake carries the albino allele. Matt mates the snake with an albino female, and four normally pigmented offspring are produced. Matt rushes back to the snake dealer and demands his money back stating that the male he bought is not heterozygous for the albino allele because all of its offspring had normal pigmentation. Is Matt justified in his accusation? O Yes, because if at least one parent is homozygous recessive, at least one of their offspring must also show the recessive trait. Yes, because 50% of all offspring produced must be albino. O No, because for each offspring, there is a 50% chance that it will have normal pigmentation. O No, because a heterozygous male will only pass the dominant allele to its offspring. Yes, because according to the laws of probability, at least one of the offspring should have been albino.
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
